This context comes from the book "Black Rednecks And White Liberals"
The heavy drain, physical and mental, in keeping squadrons on the East African coast was reflected in the loss of 282 officers and men in the ten years 1875-85; and this did not include these invalidated home
Consider these three definitions:
To make invalid; nullify. (American Heritage® Dictionary)
uczynić inwalidą (ling.pl)
- this is a definition from a Polish dictionary I'm using which says "make someone an invalid". I wasn't able to find a corresponding definition in English with "invalid" as in "disabled person". although I found this definition in Merriam-Webster which pretty much covers it:
to make invalid
especially : to weaken or destroy the cogency of.
Does the sentence in question mean that "the loss of 282 officers and men in the ten years 1875-85 did not include these which became cripples during their work and returned home" or "the count did not include the people who died at home as a result of heavy physical and mental drain during the service because someone deemed them invalid to be included in the count"?
